On Closure Properties of Read-Once Oblivious Algebraic Branching Programs
Jules Armand, Prateek Dwivedi, Magnus Rahbek Dalgaard Hansen +3
We investigate the closure properties of read-once oblivious Algebraic Branching Programs (roABPs) under various natural algebraic operations and prove the following. - Non-closure…
